Description

Control method for pluggable port of interface board and device for pluggable port of interface board

technical field

The invention relates to a communication device, in particular to a pluggable port management technology for an interface board in the communication device. the

Background technique

The interface board is a device for service input and output of communication equipment and protocol processing for services. Widely used in electronics, communications and other fields. In recent years, with the rapid development of communication technology and the continuous improvement of user requirements, the structure of communication equipment has become more and more complex, the number of interface boards for a single device is increasing, and the ports of a single interface board are also increasing. many. the

Figure 1 shows a commonly used interface board structure. As shown in the figure, this interface board includes multiple input and output ports, an optional multiplexing and demultiplexing device, a protocol processing module, a clock processing module, a logic control module, and a CPU processor. the

With the increase of the number of ports on a single interface board, in addition to requiring the interface board to be pluggable in the application, the ports of the interface board are also required to be pluggable. Correspondingly, each pluggable port requires a module. In this case, 10Gb Small Form Factor Pluggable Module ("XFP" for short), Small Form-factor Pluggable Transceiver ("SFP"), and 10Gb Ethernet Transceiver Package (10 Gigabit Ethernet Transceiver Package, referred to as "XENPAK") and other products, these modules are pluggable. FIG. 2 shows a functional block diagram of the aforementioned pluggable modules. the

As shown in FIG. 2 , the above-mentioned pluggable module mainly includes a controller, a transmitter, and a receiver. Wherein, the transmitter is composed of an optional coding and multiplexing unit, a driving unit and an electro-optical conversion unit, and the receiver is composed of an optional decoding and demultiplexing unit, an amplification unit and an optical-electrical conversion unit. the

The general structure of the interface board and the pluggable module in the prior art has been described above. Referring to FIG. 3, the pluggable port on the interface board will be described accordingly. the

Fig. 3 shows a typical circuit structure diagram of a pluggable port of an interface board in the prior art. As shown in Figure 3, pluggable ports mainly include connectors, power supply VCC, inductors L1 and L2, capacitors C1, C2 and C3, multiplexing and demultiplexing devices, logic control units, CPU units, protocol processors, resistors R1, R2 and R3 etc. the

Among them, the connector is used to connect the pluggable module and other components of the pluggable port; the power supply VCC is used to supply power to the pluggable module; inductors L1 and L2, and capacitors C1, C2, and C3 are used for power filtering; The demultiplexer is used to synthesize multiple channels of low-rate data into one channel of high-rate data and decompose one channel of high-rate data into multiple channels of low-rate data in the opposite direction. It should be noted that the multiplexing demultiplexer is optional; logic The control unit is used to detect and control the logic status of pluggable modules, multiplexing and demultiplexing devices, CPU units and protocol processors; the CPU unit is used to control the logic control unit and protocol processor; the protocol processor is used to control the input The output data is processed; the resistor R1 cooperates with the pins D and E of the logic control unit and the presence detection line of the pluggable module to detect whether the pluggable module is in place. When the pluggable port of the interface board shown in Figure 3 is working, the pin D of the logic control unit outputs a high level, and the pin E of the logic control unit detects the state of the input level. When the input level is detected to be a high level, Indicates that a pluggable module is not present. After the pluggable module is inserted, the presence detection line of the pluggable module pulls the level low, and the pin B of the logic control unit detects that the input level is low, indicating that the pluggable module is in position. the

In practical application, the above solution has the following problems: when the user adds a large number of pluggable modules arbitrarily on the interface board, or replaces the pluggable modules at will, it may cause device and network instability. the

The main reason for this situation is that there is no management on the insertion and replacement of the pluggable modules, and there is no effective authority control to prevent the pluggable ports of the interface board from being misused or illegally used. the

Contents of the invention

In view of this, the main purpose of the present invention is to provide a control method for the pluggable port of the interface board and a device for the pluggable port of the interface board, so that the illegal use of the pluggable port of the interface board can be effectively avoided, and the communication equipment can be better guaranteed. and the stability and reliability of the communication network. the

Wherein, the one or more switches enable or disable the pluggable port of the interface board by connecting or turning off the power switch of the pluggable port of the interface board. the

The one or more switches enable or disable the interface board pluggable port by connecting or disconnecting a switch of a transmitter data input of the pluggable module or a switch of a receiver data output of the pluggable module. the

The logic control unit enables or disables the pluggable port of the interface board by changing the input level of the shutdown control pin of the pluggable module transmitter to be high or low. the

In addition, the pluggable port device of the interface board also includes a multiplexer/demultiplexer, which is connected between the protocol processor and the connector, and is used for synthesizing multiple low-rate data into one high-rate data and returning The direction decomposes one channel of high-rate data into multiple channels of low-rate data. the

Through comparison, it can be found that the difference between the technical solution of the present invention and the prior art is that by setting a password for the pluggable port of the interface board and setting the pluggable port to a disabled state, the use of the pluggable port is restricted And replacement, only when the correct password is entered, the pluggable port of the interface board is allowed to be enabled. In addition, by adding one or more switches to the pluggable ports of the interface board, the management of enabling and disabling the pluggable ports is realized through the control of the logic control unit. the

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. the

Fig. 4 is a schematic flowchart of setting a password and a disabled state for a pluggable port of an interface board in a method for controlling a pluggable port of an interface board according to an embodiment of the present invention. The main process of this process is to read the serial number of the interface board and the maximum number of pluggable ports M of the interface board during the production process of the interface board, that is, the upper limit of the number of pluggable ports that the interface board can accommodate, and then give each The password is set by plugging and unplugging the port, and the password is stored in the internal memory of the interface board. Among them, the serial number is the unique identification of the interface board. The serial number is also pasted on the handle of the interface board and stored in the memory of the interface board and in the production database. The details of the interface board can be queried in the production database through the serial number. Information such as port passwords, date of manufacture, etc. the

Thereafter, set these pluggable ports to disabled state. At the same time, store the serial number of the interface board and the password of each pluggable port in the production database. The production database is used to record a series of data generated during the production process of the equipment and its board, such as: equipment Configuration, board information, etc. The production database is a database used by equipment manufacturers to store production process data. the

Specifically, as shown in Figure 4, in the process of setting passwords for the pluggable ports of the interface board, at first, in step 100, read the serial number of the interface board, and the maximum number of pluggable ports M of the interface board ; Then enter step 110, set the pluggable port number X to X=1; then enter step 120, set a password for the pluggable port X, and set the maximum number of password input times Q for the pluggable port. The maximum number of password input times Q indicates the number of times that the password is allowed to be entered incorrectly. If the maximum number of password input times Q is exceeded, the system will no longer allow the user to change the state of the pluggable port. This will be described in detail below. the

It should be noted that at the same time, at step 170, the serial number of the interface board and the passwords set for each pluggable port are respectively stored in the production database. the

After this enter in step 130, will in step 120 be the password that pluggable port X is provided with, and the maximum number of times of password input Q of this pluggable port is stored in the internal memory of interface board; Enter step 140 afterwards, this The state of pluggable port X is set to disabled state, that is, any pluggable module plugged into this port cannot work normally. Thereafter, enter step 150, judge whether the pluggable port number X is greater than or equal to the maximum number of pluggable ports M on the interface board, if yes, it means that all pluggable ports on the interface board have been password-protected and disabled settings, the process ends. Otherwise, it means that there are still pluggable ports that have not been set above, go to step 160, set the pluggable port number X as X=X+1, and return to step 120 to continue setting. the

It should be noted that, in the above process, the control of the input level of the "transmitter shutdown control" can be realized through the logic control unit in the pluggable port of the interface board, thereby realizing the "disabling" of the pluggable port. "set up. Specifically, when the "transmitter shutdown control" input is at a high level, the transmitter will be turned off, that is, enter the "disabled" state. When the "transmitter shutdown control" input is low, the transmitter will be turned on, that is, in the "enabled" state. During the production process of the interface board, the level of the "transmitter shutdown control" can be set to a high level according to the setting of "disabling" in the above process, and the reset of the logic control level can be prohibited, thereby realizing "Disable" controls for pluggable ports on interface boards. When the pluggable port needs to be enabled, after entering the correct password of the pluggable port, the logic control unit will set the level of "transmitter shutdown control" to low level, and allow the logic level to be reset , which is enabled. When the above process is implemented in this manner, no modification is required to a typical pluggable port circuit. the

In the pluggable port device of the interface board according to an embodiment of the present invention, as shown in Figure 11, a switch K1 can be added on the "input power supply VCC" of the pluggable port, and the switching state of this switch K1 is determined by logic Control unit control. In the production of the interface board, according to the setting of the "disabled" state of the pluggable port, the logic control unit sets the state of the switch K1 to an open state, and prohibits the switch from being reset, thereby realizing the pluggable port. "Disable" control. When the pluggable port needs to be enabled, after inputting the correct password, the logic control unit sets the state of the switch K1 to the closed state and allows it to be reset, that is, it is in the enabled state. the

In addition to the above two implementation methods for setting the disabled state, the present invention also proposes several pluggable port devices of the interface board. The first one is as shown in FIG. 12 , a plurality of switches K1 - Kn can be added to the pluggable port "send data input", and the switch states can be controlled by a logic control unit. In the production process of the interface board, according to the setting of the "disabled" state of the pluggable port, the logic control unit sets the state of the group of switches to an open state, and prohibits the group of switches from being reset, thereby realizing the "disabled" control . When the pluggable port needs to be enabled, when the correct password is entered, the switch state is set to the closed state, and the group of switches is allowed to be reset, which is the enabled state at this time. The second type is shown in FIG. 13 , adding a plurality of switches K1 ˜ Kn to the pluggable port “received data output”, and controlling their switch states through a logic control unit. During the production process of the interface board, according to the setting of the "disabled" state of the pluggable port, the state of the group of switches is set to an open state through the logic control unit, and the reset of the group of switches is prohibited, thereby realizing the pluggable port. Unplug the "disable" control of the port. When the pluggable port needs to be enabled, after inputting the correct password, the logic control unit sets the state of the switches K1-Kn to the closed state and allows them to be reset, that is, they are in the enabled state. the

In a word, through the process described in FIG. 4 , passwords can be set for all pluggable ports on the interface board one by one, and these pluggable ports can be set to a disabled state. the

Fig. 5 shows a process of inserting a pluggable module in a method for controlling a pluggable port of an interface board according to an embodiment of the present invention. To put it simply, in this process, when it is detected that a pluggable module is inserted, it is detected whether the pluggable port is enabled. If it is enabled, it will end directly. If it has not been enabled, a password prompt box will pop up and wait for the input to be correct. After the password is passed, the pluggable port changes to the enabled state, and the password input counter is cleared to zero. It should be noted that after the number of consecutive wrong password input reaches the set maximum number of password input times, the system will prompt an error, and the password input counter will be cleared to end the program to prevent wrong or illegal use. the

Specifically, the process is shown in Figure 5. During the use of the communication device, when a pluggable module is inserted into the pluggable port of the interface board, the pluggable port X of the pluggable port X is first detected in step 200. Pull out the module in place; enter step 210 thereafter, judge whether this pluggable port X has been enabled, if enabled, then do not perform any operations and end directly, otherwise, if this pluggable port X has not been enabled, then enter step 220, Read the maximum password input times Q, as mentioned above, in the password and disabled state setting process, the maximum password input times Q has been set and stored in the internal memory of the interface board. Then enter step 230, set the password input counter Y as Y=1. Then enter step 240, input the password of the pluggable port X, in this step, the system will pop up a password input prompt box. Then enter step 250, according to the password of the pluggable port X stored in the memory in the interface board, judge whether the password of the pluggable port X input is correct, if correct, then enter step 260, enable the pluggable port X, The pluggable port X is changed to the allowed state, and the password input counter is cleared to zero, and the process ends. Otherwise, if the password is inaccurate, go to step 270, and the system pops up a prompt box, prompting that the password is incorrectly input, and sets the password input counter Y as Y=Y+1. Then enter step 280, judge according to the password input counter whether the number of password input times is greater than or equal to the maximum number of password input times Q set in the above password and disabled state setting process. If yes, it means that the number of wrong password input has reached the set upper limit, the system will prevent the normal use of the pluggable module, and the process will end directly. Otherwise, return to step 240 and input the password of the pluggable port X again. the

Through the process in Figure 5, it is possible to enable the pluggable port by entering the correct pluggable port password, and at the same time prohibit the user who continuously enters the wrong password from wrongly using or illegally using the pluggable port on the interface board.

Fig. 6 is a schematic flowchart of enabling or disabling a pluggable port in a method for controlling a pluggable port of an interface board according to an embodiment of the present invention. According to the present invention, when the interface board is in use, a certain pluggable port can be enabled or disabled regardless of whether there is a pluggable module on the pluggable port. First, you need to enter the password of the pluggable port. If the password is correct, choose whether to enable or disable the pluggable port. If you choose to enable, enable the pluggable port and end the program; Whether the pluggable module of the pluggable port is in place, if not in place, the pluggable port is disabled, if in place, the system sends a prompt box to prompt the user to re-select whether to disable the pluggable port. If the user selects "Yes", the pluggable port is disabled and the program ends. If "No" is selected, the program will end directly. It should be noted that if the number of wrong password input exceeds the preset maximum number of password input times during the above setting process, the system will prompt and reset the counter to zero to end the program. the

Specifically, as shown in Figure 6, in step 300, the state of the pluggable port X on the interface board is prepared to be modified; after this, enter step 310, and read the maximum number of times Q of password input, as mentioned above, in the password and disabled state settings This parameter has been set in the process. Then enter step 320, the password input counter Y is set to Y=1; then enter step 330, enter the password of pluggable port X; , to determine whether the input password is correct, if correct, enter step 370, otherwise enter step 350. the

In step 350, the system prompts that the password is wrong, and sets the password counter Y as Y=Y+1; then enters step 360, and judges whether the password input times Y is greater than or equal to the maximum password input times Q, if yes, it means continuous input errors The number of passwords has reached the upper limit set, so the process is ended directly. If not, return to step 330 and re-enter the pluggable port X password. the

In step 370, it is determined whether to disable or enable the pluggable port X. If it is enabled, go to step 380 to enable the pluggable port X, and the process ends; if it is disabled, go to step 390 . the

In step 390, it is judged whether the pluggable module of the pluggable port X is in place, if not in place, go to step 400, disable the pluggable port X; if in place, go to step 410. the

In step 410, the system prompts that the pluggable module of the pluggable port X is in place, and asks to confirm whether to disable the pluggable port X. If it is confirmed that the pluggable port is not disabled, the process ends directly; if it is confirmed that the pluggable port X is disabled, then enter step 420, disable the pluggable port X, and the process ends. the

In the process shown in FIG. 6 , the pluggable port can be allowed to be enabled or disabled by inputting the correct password, and at the same time, wrong use or illegal use can be prevented. the

In another embodiment according to the present invention, the pluggable ports and passwords of the interface board do not uniquely correspond to each other, and the same password controls one or more pluggable ports. the

The main steps in this process include setting one or more passwords for the interface board, where each password is used to enable or disable one or more pluggable ports. Then store the set of passwords in the internal memory of the interface board, and set all pluggable ports on the interface board to a disabled state. At the same time, the number of pluggable ports that are allowed to be enabled and the number of pluggable ports that have been enabled are cleared. In addition, the serial number of the interface board, the set of passwords and the number of pluggable ports that can be controlled by each password are stored in the production database. the

Specifically, as shown in Figure 7, in step 600, read the interface board serial number; After this enter step 610, set the password quantity I of this interface board, namely the total number of passwords that this interface board is set; Then enter step 620, set The code number is J=1. Then enter step 630, set the password J and the number N of pluggable ports that can be controlled by the password J, that is, the total number of pluggable ports that the password J can control. At the same time, in step 640, the serial number of the interface board, the set password J and the number N of controllable and pluggable ports are respectively stored in the production database. the

Then enter step 650, store the above-mentioned password J and the number N of controllable pluggable ports in the internal memory of the interface board; then enter step 660, judge whether J is greater than or equal to the number I of the password, if not, then enter step 670, Set the code number J as J=J+1, and return to step 630 . If yes, then enter step 675, and all ports are set to be disabled. Then enter step 680, set the number of pluggable ports allowed to be enabled as 0, and enter step 690, set the number of enabled pluggable ports as 0, and the process ends. the

Fig. 8 is a schematic flowchart of enabling a pluggable port after the interface board is powered on or reset in a method for controlling a pluggable port of an interface board according to another embodiment of the present invention. This process mainly includes checking whether all pluggable ports with existing modules are enabled. If the pluggable port is not enabled and the user chooses to enable it, then check whether the number of pluggable ports allowed to be enabled is greater than the number of enabled pluggable ports. The number of pluggable ports, if it is greater than, enable the pluggable port and modify the counter of the enabled pluggable port. If it is equal, prompt to enter the password, and verify the password. After entering the correct and unique password, increase the number of pluggable ports that are allowed to be enabled, enable pluggable ports and modify the counter of pluggable ports that are allowed to be enabled. . Specifically, as shown in FIG. 8 , in step 701, the enabled pluggable port counter S, the enabled pluggable port counter U, the maximum number of pluggable ports M on the interface board, and the maximum password input are respectively read. The number of times Q. Wherein, the counter U of the pluggable ports allowed to be enabled indicates the total number of pluggable ports that can be enabled on the interface board by each password that has been set to be enabled. Then enter step 702, the current pluggable port number X is set to X=1; then enter step 703, determine whether the pluggable port X has been enabled, if so, then enter step 717, otherwise, enter step 704. the

In step 912, it is judged whether the password has been disabled, if so, the process ends, otherwise enter step 913;

In step 913, it is determined whether the number of pluggable ports enabled is less than or equal to the difference between the number U of pluggable ports allowed to be enabled and the number N of password-controlled pluggable ports, if yes, then enter step 914, otherwise enter step 913. 915;

In step 914, the password is disabled, and the pluggable port is allowed to be enabled, and the number of pluggable ports allowed to be enabled is set to U=U-N, and the process ends;

In step 915, display enabled pluggable ports, and whether there is a pluggable module in place, enter step 916;

In step 916, input the pluggable port number that needs to be disabled, and enter step 917;

In step 917, it is judged whether there is a pluggable module in place on the pluggable port, if there is, then enter step 918, otherwise, enter step 919;

In step 918, judge whether need to disable this pluggable port, if yes, then enter step 919, otherwise enter step 920;

In step 919, the pluggable port is disabled, and the number M of enabled pluggable ports is set to M=M-1;

In step 920, determine whether to stop the process, if yes, end the process, otherwise return to step 913. the
